Bears are territorial in nature. One of their rituals includes dragging their claws through tree bark to alert potential predators that the territory is taken. Here at BCA we recognize that when it comes to barrels no one else does it better.
"This is both our challenge and declaration."
The bear claw embodies our commitment to superior barrel technology.
Its just an extra that it looks so cool.
